Long-running BBC children's programme that featured game segment Double or Drop (11)

I believe the answer is:

crackerjack

(Other definitions for crackerjack that I've seen before include "Wonderful (person or thing)" , "Excellent (person or thing)" , "Exceptional (thing or person) - 1970s' children's programme" , "Exceptionally good" .)

I've seen this clue in The Mirror.
